Amino Acid Sequence

Phe-Cys-Tyr-Trp-Orn-Thr-Pen-Thr-NH2 [Disulfide Bridge: 2-7]

Description générale

D-Pen-Cys-Tyr-D-Trp-Orn-Thr-Pen-Thr-NH2 (CTOP) is a selective cyclic μ-opioid receptor antagonist.

Application

CTOP has been used:
  • to study the anxiogenic effects induced by CTOP in mice and rat.
  • to study the effect of μ-opioid antagonist, CTOP on the bovine milk-derived LF (BLF)-induced analgesia.
  • to determine whether μ-opioid receptors act cooperatively with 5-hydroxytryptamine (5-HT1A) receptors to regulate the behaviors generated in the elevated T-maze (ETM).

Actions biochimiques/physiologiques

D-Pen-Cys-Tyr-D-Trp-Orn-Thr-Pen-Thr-NH2 (CTOP) inhibits acute morphine-induced hypermotility and analgesic effect of morphine in a dose-dependent manner in vivo.
Selective ligand for μ-opioid receptors.

Liaison

Ethanol consumption is considerably elevated during adolescence. Attractiveness of alcohol for humans during the adolescent developmental period is based, in part, on its ability to induce social facilitation--a facilitation of social interactions not only evident in human adolescents but also

Painful stimuli activate nociceptive C fibers and induce synaptic long-term potentiation (LTP) at their spinal terminals. LTP at C-fiber synapses represents a cellular model for pain amplification (hyperalgesia) and for a memory trace of pain. μ-Opioid receptor agonists exert a

Aim: To examine the effects of fentanyl, a potent mu-opioid receptor (MOR) agonist, on-air puff-evoked responses in Purkinje cells (PCs), and molecular layer interneurons (MLIs) using in vivo patch-clamp recordings in anesthetized mice. Methods: Male mice 6-8 weeks-old were anesthetized

Although the classical function of myelin is the facilitation of saltatory conduction, this membrane and the oligodendrocytes, the cells that make myelin in the central nervous system (CNS), are now recognized as important regulators of plasticity and remodeling in the
